安裝cocoapods問題彙總

sudo gem install cocoapods
           

安裝後，發現輸完密碼一直沒動靜。問題是因為“https://rubygems.org/“被牆了，更換gem源為“https://gems.ruby-china.org/“即可：

gem sources --add https://gems.ruby-china.org/ --remove https://rubygems.org/
           

再次執行“sudo gem install cocoapods“仍然報錯：

ERROR:  While executing gem ... (Gem::DependencyError)
    Unable to resolve dependencies: cocoapods requires cocoapods-core (= ), cocoapods-downloader (< , >= ), cocoapods-trunk (< , >= ), molinillo (~> ), xcodeproj (< , >= ), colored (~> ), escape (~> ), fourflusher (~> ), gh_inspector (~> ), nap (~> ), ruby-macho (~> ); activesupport requires i18n (>= , ~> ), tzinfo (~> ), minitest (~> ), thread_safe (~> ); cocoapods-plugins requires nap (>= )
           

出現這個問題是因為ruby版本太低，執行：

接着報錯：

Updating rubygems-update
Fetching: rubygems-update-.gem (%)
ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.
           

報這個錯是因為權限不夠，加上sudo：

sudo gem update --system
           

接着就開始babala，開始安裝了：

Updating rubygems-update
……
……
……
ERROR:  While executing gem ... (Errno::EPERM)
    Operation not permitted - /usr/bin/xcodeproj
           

撞到最後又丫的報錯啦。網上搜尋了一下，解決方案是：

sudo gem install -n /usr/local/bin cocoapods
           

坑有點多，也不怕吓壞小朋友，真是的……
